The automatic shape determination method for reproducing cursive Arabic script, as described in Canadian Patent 1,207,905 employs a finite state machine including one state, (E), enabling the reproduction of Arabic characters in basic or standalone shape for initials, acronyms, etc. However, in products whwere Arabic data is stored in "shaped" form (as with X/BASIC), or in "unshaped" form when using ASMO 449, two problems arise. When using X/Basic, where text requires revision, any data stored in basic mode will be shaped during revisions, i.e., there is no way of telling that certain of the data must be retained in basic or standalone shape. With products using code pages based on ASMO 449, the basic mode is not supported because generated script is stored in "unshaped" format.
